Light sensor

The light sensor realizes a partially automated driving light control system that is standard equipment in most new vehicles. The incident light is measured by an optoelectronic element or light sensor and evaluated by control electronics. Depending on the result of the evaluation, the low beam is switched on or off. This function is now fully implemented by the handy module "light sensor" and can be retrofitted into your existing lighting wall on CAN basis in a few seconds. Thus, the partially automated driving light control is also available to you in training and offers you further measurement possibilities, so that the system can be understood holistically.

Extended functions through the light sensor:

• Partially automated driving light control
